Satan steps out first to establish his prominence and, in truth, without his presence (and the great buck-and-wing he shares with God midway through, which deserved an instant encore)it would be a much less entertaining piece of Biblical whimsey. Propelled by a simple, charming song score (like THEFANTASTICKS) the introduction of Steve into the story (“adapted” from Genesis) is cute and sometimes self-consciously jokey, but remarkably Retro in its attitudes. It’s moving directly into a two-month run (in NoHo, NOT WeHo) and will probably do very well indeed. The cast is all strong and very well-chosen—-but before they embark on a long-term regular run Adam&Eve&Steve would be well-advised to head for tanning salon—-right NOW.
